HEATING-DRUM.

Specification of Letters Patent.

Patented June 1, 1915.

Application filed June 6, 1914. Serial No. 843,355.

T all whom it may concern:

Be it known that I, LYMAN L. MOORE, a citizen of the United States, anda resident of Seattle, in the county of King and State of Washington,have invented certain new and useful Improvements in Heating- Drums, ofwhich the following is a specification.

This invention comprehends certain new and useful improvements inheating drums and has for its primary object to provide a device of thischaracter which will be constructed in such manner that it may bereadily incorporated in the stove pipe and W111 cause such circulationof the products of combustion as to heat the drum and thereby cause anincrease of temperature in the room or other inclosure through which thestove pipe extends.

Another object is to provide a device of this character in which will beincluded vertical and transverse partitions provided with openings and adamper carried by one of the said partitions and adapted for engagementover one of said openings, whereby the products of combustion may bepermitted to travel directly to the upper end of the heating drum orcaused to circulate around and between the partitions to heat the drumproper, as desired.

A further object of this invention is to provide a device of thischaracter which will be of extremely simple construction and op erationand highly ei'ficient in use, as well as cheap to manufacture.

With the above and other objects in View, as will become more apparentas the description proceeds, the invention consists in certain novelfeatures of construction, combination and arrangement of parts as willbe hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had tothe following description and accompanying drawings, in which,

Figure 1 is a longitudinal central section through the complete devicein position in a stove pipe. Fig. 2 is a top plan view of the partitionremoved from the drum proper and showing the damper positioned over itsopening. Fig. 3 is an elevation of the same and Fig. 4 is a bottom planview of the entire device.

Referring now more particularly to the drawings, reference numeral 1designates the drum proper, which may be constructed of two sections andconnected by flanges 1 and bolts 1 to permit of assembly of the severalparts. Said drum is of cylindrical form and has its lower edge reducedto a nipple 2 which projects downwardly from the center of the bottom ofthe said drum, for engagement with the stove pipe section 3. The nipple4 is a duplicate of the nipple 2 except that it is formed on the upperend of the said drum, and it projects upwardly therefrom for engagementwith the pipe sec tion 5, as will be readily understood by referring toFig. 1.

Positioned in the drum proper 1, and extending longitudinally therefromis the vertical partition 6, the lower end of which is spaced above theupper open end of the nipple 2 to allow the products of combustionentering the drum proper 1, by way of the said nipple 2, to pass saidpartition and enter the large front chamber 7, at the upper end of whichis positioned a transversehorizontal partition 8 which is of circularform and fits snugly against the inner circular surface of the saiddrum. The vertical partition 6 has an opening 9 through the; same whichis adapted to be closed .by a. damper plate 10 when the latter is inclosed or operative position. The damper plate 10 is mounted upon andcontrolled by a damper rod 11 passing through one end of the said damperplate and rotatably mounted through the wall of the drum proper 1, andhaving a handle 12 formed upon one end whereby the said damper rod maybe readily rotated in either direction to move the damper plate 10 toclosed or open position as desired.

When a straight draft is desired the damper plate 10 is swung to openposition, thereby allowing the products of combustion to travel throughthe front chamber 7 and pass from the same by way of the openings 9thence through an upper central opening 13 in the transverse partition 8and through the nipple 4: to the upper pipe section 5.

When it is desired to cause a circulation of the products of combustionwithin the heating drum to heat the surrounding atmosphere and increasethe temperature in the room or other inclosure within which the heatingdrum is positioned, the damper plate 10 is swung to closed position asclearly shown in Fig. 1, thereby causing the products of combustionentering the front chamber 7 and passing to the upper end thereof, topass through side openings 14: in the upper portion of the partition 6and below the transverse horizontal partition 8 forming the top of thefront compartment 7.

After the products of combustion have end of said compartment 18, to thenipple 4: and upper pipe section 5. It will be understood that theoutwardly turned lower ends 16 0f the partitions 17 are for the purposeof retarding the circulation of the products of combustion, thusallowing more heat to be absorbed by the drum proper before saidproducts of combustion pass on to the pipe 5 and that said upturned ends16 are suitably spaced above a lower transverse horizontal partition 19forming the bottom of the compartments 15 and 18 and preventing theproducts of combustion entering the drum proper 1 from passing directlyinto the lower end of said compartments 15 and 18. It will be furtherreadily apparent that this circulation of the products of combustionaround and through the partition 6 will heat the drum proper 1 andthereby cause an increase in temperature of the air coming in contactwith the outer face of said drum proper. v

From the foregoing it will be seen that I have provided a heating drumof extremely simple construction and operation and which will be highlyeflicient in use and may be readily incorporated in the stove pipe orthe like or removed from the same.

While I have shown the preferred embodiment of my invention it will beunderstood that minor changes in details of construction and arrangementof parts may be made within the scope of the appended claim withoutdeparting from the spirit of my invention or sacrificing any of theadvantages thereof.

Having described my invention, what I claim as new and desire to protectby Letters Patent is- A device of the character described including acasing, said casing having a central nipple at its lower end and anipple at its upper end, the upper of which is offset with respect tothe vertical center line of the drum proper, a vertical partition havinga draft opening within said casing, a transverse partition provided witha draft opening positioned in said casing a spaced distance from theupper end thereof and connected with one end of the vertical partition,a pair of vertical partitions projecting from the face of the firstmentioned vertical partition, the lower ends of the last named verticalpartitions being spaced above the lower ends of the first mentionedvertical partition, a transverse horizontal partition connected with thelower end of the first mentioned vertical partition and the adjacentwall of the casing, said last mentioned transverse horizontal partitionbeing positioned beneath the second mentioned vertical partitions, saidfirst mentioned vertical partition having openings below the firstmentioned transverse horizontal partition, and a damper plate positionedupon the first mentioned vertical partition and adapted to cover one ofthe said openings.
